Zombies return to the "Death Swamp" in their relentless pursuit for brains today, as Activision and developer Treyarch released Call of Duty: World at War: ZOMBIES II, an adaptation of the popular "Shi No Numa" map for the iPhone and iPod touch. Here is more info about this new iPhone game:

Originally released as downloadable content for one of the most popular and played online games of 2009, Call of Duty: World at War, ?Shi No Numa? gives players new characters, a massive new location, the deadly new Wunderwaffe DG-2, new traps, and the addition of Hellhounds to the attacking legions of Undead. This new app is available for $9.99 through the app store, but fans who own the original Call of Duty: World at War: ZOMBIES can download ?Shi No Numa? as an In-App Purchase for $4.99.

The ?Verr?ckt? map, also developed by Ideaworks Game Studio, is available for $4.99 from the main menus of both Call of Duty: World at War: ZOMBIES and Call of Duty: World at War: ZOMBIES II.
